COATING COMPOSITION OR PAINT.

No Drawing. Application filed July 30,

To all whom it ma 3 concern:

Be it known that 1, Moss R. ISAACS, a citizen of the United States, anda resident of the city of Philadelphia, county of Philadelphia, andState of Pennsylvania, have invented certain new and useful Improvementsin Coating Compositions or Paints. of which the following is a full,clear, and com let/e disclosure.

l\ y invention relates to a composition of matter adapted for use as acoating substance or paint or the like and preferably relates to thatclass of coating compositions or paints which are soluble in water or inan alkaline solution and which are generally known under the name ofwater aints.

An object of my invention is 0 prot uce such compositions from aproteinous, albuminous, gelatinous or similar substances or a mixture ofmaterials or ingredients including such substances as an essential partthereof and I preferably produce the same from a proteid or a mixture ofproteids. such as alb i i fm ngalbuminoidsafid cases? or compositionscontaining the same as an essential element thereof. such as caseinglues, casein sizings, and similar materials.

Another object of my invention is to produce such compositions. withcertain ingredients or chemicals, which will be adapted to be applied asa coating. paint or the like to any adaptable surface, such as,

plaster, concrete, cement, stone,,hricks, wood, metal, fabrics, hides.leather,

er and simi ar substances or objects.

A further object of my invention is to produce a composition of thecharacter aforesaid which will also possess, in an unusually highdegree, the quality or property of resisting the effects of the weatheror climate, making themwof, also of high and cold temperatures, as mayresult from the action of the sun, fires, frost and freezing conditions,physical and chemical effects, as may arise from the action of fumes,vapors, gases and the like and of dampness, moisture, humidity, waterand the like.

A still further object of my invention is Specification of LettersPatent.

Patented Aug. 8, 1922.

1919. Serial No. 314,363.

to provide a composition possessin in addition to the above mentioned caracterist-ics, the property of being very adherent, flexible, durable,sanitary, germ and insect proof and the like.

Astill further object of my invention is to produce a composition of thecharacter aforesaid and which will also possess preservative and germ orinsect repellent properties, as well as other characteristics, such as adeep tone or color, increased binding power and excellentweather-proofing properties.

Other and further objects of my invention will be more fully disclosedin the following specification.

I have discovered that by combining with a )roteid or a mixture ofproteids, and more particularly casein or compounds containing casein asan essential element thereof, certain proportions of an alkaline earthcompound, such as lime, and a soluble fluoride or soluble compoundscontaining uorlne, witlfor without a compound or w of the alkaline earthchemical rou 3, such as, calcium and ma nesium. and more particularlyglg an. ement and .%sbestine.' or compounds"con amin the 1 02 gs calciumz 1 n d ma nesium. such as for example, ce- 80 .,a men an ortland came?that a coating composition is obtaine w 1ch possesses thecharacteristics, hereinbefore enumerated, particularly suited for use asa water paint.

In carrying my invent-ion into practice I preferably mix a proteid, aproteinous substance, or an albuminoid, such as casein, ca or compoundscontaining casein as an essential element thereof with an alkaline earthcompound, such as lime, and a soluble fluoride or a soluble compoundcontaining fluorine. To this I add, depending upon the particular use towhich the coating composition or paint is to be put or the particularsurface or object to be treated, certain filling, carrying and bindingingredients, such as compounds containing calcium and magnesium,compounds containing the silicates and aluminates of calcium and mag-100 z 4 4 iaj Exama nesium, plaster of Paris Asbestine, argillaceousaterials such as c av, cements, particularly P tland cemen an variouscolorin materialsprefera y minera golgrs.

In compounding or producing suci compositions, I do not wish to limitmyself, except as herein otherwise indicated, in the particular amountsor number of the ingredients entering therein since the surfaces towhich the composition is to be applied as well as the conditions towhich the composition is to be subjected, require different Droportionsof the various ingredients and su stances constituting the composition,to secure the best results for the purpose intended.

I find that such composition may be suitably produced by mixing in theproportion by weight from five (5) to twenty (20) parts of casein fromfive (5) to sixty (60) parts of om one half (a) to five (5) parts 0 afluoride or a compound containing fluorine, preferably sodium fluoride,from one half to ten parts 0 a s1 1- cate, preferably sodium silicateand from twenty (20) to eig ity t parts of any one or a mixture of anyof the following ingredients; a Paris. c av. cement or ot ier com oun s0 calcium or ma nesium, or compounds To The silicates and aluminates ofcalcium and ma nesium, an rom a mmu o t on o colorin matt depending uponthe shade or tint of the color desired. In adding colorin matter acertain relation of the prop ortions between the same and the plaster ofaris and Asbestine is maintained, in that, when more or less coloringmatter is adde l, proportionately less or more plaster of Paris andAsbestine respectively is included in the composition. To the abovemixture I then add an eg ual amo unt of and p rmit the mass to stam fora on 1 een (15) minutes prior to using the same as a coating compositionor a paint.

I have discovered, however, that when the composition is used upon ametal or similar surface better results are obtained by decreasing thesodium silicate ingredient, while on the other hand, if the same be usedas an inside paint I have found that the inclusion of only Asbestine asa filler will give very goo s resu s, an t a or use as an outside painta lar er )ortion of laster of Paris is necessarv to no uce or oreparticular y, for a composition for eneral use or.adaptation, such asfor coatmg or painting wood, fabrics, cloth, cement, plaster and thelike, I mix the component substances in the proportions by wei ht offifteen (15) parts of ca ein wenty 20) parts of lime three (3) par of afluoride. preferably sodium fluo one (1) partof sodium silicae en 10)parts of Ashes- YWMLLM amount of wat I have oun however, that a veryefficient and efficacious composition including a large portion ofiortland cement may be produced, in the proportions by weight of fifteen(15) parts of casein. twenty (20) parts of lime. three (3) parts ofsodium fluoride, one part of sodium silicate iiftv tnrty (30 and anequal loll; parts of Portlan c parts of coloring matter amount of water.

Of these formulae, for certain purposes, as for coating metal and thelike, the sodium silicate constituent may be omitted.

'ln the above it will be observed that the lim included in a preferablylarge proportion, the reason for this being for the same to act as asolvent for the )roteids. the albuminoids or the casein and yet to leavea su c1en quan 1 y iereo to insure a complete chemical reaction betweenthe same and the other chemicals entering into the composition.Moreover, in the case of coatmg or painting cements. plaster, stone,

%;i ck5 and tlie'l1ke the llll'ltm H uriher a' c'ts a binder between theingredients of the coating composition and the material of the objectscoated.

I have further discovered that by adding, to any of the above mentionedcompositions. from one half (9;) to five (5) parts by weight ofnaphthalene that the "keeping property 0 e coa mg composition or paintis improved and also that the addition of the naphthalene has a tendencyto prevent gangs. moths and the like from attacking or a hering to suchcomposition or any surface coated thereby.

I have also discovered that by adding from five (5) to twenty (:20)parts by weight of an oil. such as a mineral or parafiine oil. a

coal-tar oil. a ve etab e Oil or an anima oil 1e 1'6 or oti tmjm given adee )er color. and better water-proofing properfies.

The naphthylic ingredient and the oil may be added either at the timewhen preparing or mixing the ingredients to form the aforesaidcomposition or at the time when the said composition is used to coat orpaint any of the objects or articles herein mentioned.

lVhile I have described the manner in which my coating composition orpaint may be produced, these descriptions are intended as exemplifyingrather than limiting my invention and it is to be understood that thematerials, their proportions, the number enumerated, and the mode oftreatment may be suitably varied without departing from the spirit of myinvention and the scope of the appended claims.

Having thus described my invention what 106. cowosmofls,
